AC installation charges in India: copper pipe per foot, stand, core cutting and what 'free installation' covers

A split AC installation bill in India usually has two parts: a basic installation (mounting the indoor and outdoor units, connecting a standard length of copper pipe, drain pipe and cable, vacuuming and starting the unit), which may be free or bundled with the purchase, and extras billed separately: extra copper pipe beyond the standard length (charged per foot or per metre), an outdoor stand or wall bracket, core cutting through a thick wall, extra drain pipe, electrical work and sometimes extra gas for long pipe runs. GST is generally added to the service. Get the brand's or installer's rate card in writing before work starts and check the pipe length actually used.

What standard installation typically covers

Brand and dealer packages differ, so read your own invoice and installation terms. A typical split AC package includes:

Fixing the indoor unit on the wall with its mounting plate
Placing the outdoor unit on an existing surface, or on a bracket if supplied
Connecting a standard pipe kit, often a few metres of insulated copper pipe pair supplied with the AC
Drilling a standard hole for pipes, drain and cable through a normal brick wall
A short drain pipe
Vacuuming the lines (removing air and moisture) and releasing the factory gas charge
Test run and a demonstration

Not usually included: extra pipe, a stand or a heavy-duty bracket, core cutting through RCC or a thick wall, long drain runs, extra electrical points or cable from the distribution board, a stabiliser, scaffolding or rope access for high outdoor units, and removal of an old AC.

Window AC installation is simpler: the box is fitted in a window or wall cut-out with a frame or support. Extras arise mainly from making or modifying the opening.

Typical extras and how they are priced

Item	Usually priced as	Why it varies
Extra copper pipe with insulation	Per foot or per metre	Pipe diameter (by tonnage), wall thickness of copper, insulation quality, copper price
Outdoor unit stand or bracket	Per piece	Wall bracket vs floor or roof stand, material
Core cutting	Per hole	Wall thickness, RCC vs brick
Extra drain pipe	Per foot or metre	Length and routing
Electrical cable, MCB, socket	Per item or per metre	New point needed or existing one usable
Extra gas for long runs	Per run or per weight	Pipe length beyond what the factory charge covers
Uninstallation of old AC	Per unit	Split or window; gas recovery
High-rise or difficult access	Lump sum	Rope access, ladders, safety equipment

Worked estimate (illustrative)

A 1.5-ton split in a second-floor bedroom. The outdoor unit goes on a wall bracket on the side of the building, needing 13 feet of pipe more than the standard kit.

Item	Calculation (illustrative rates)	Amount
Basic installation	Included with purchase	₹0
Extra copper pipe	13 ft × ₹240	₹3,120
Wall bracket	1 × ₹1,100	₹1,100
Core cutting through 9-inch wall	1 × ₹700	₹700
Extra drain pipe	10 ft × ₹25	₹250
Subtotal		₹5,170
GST at 18%		₹931
Total		₹6,101

Try your own numbers in the installation cost estimator. Enter the extra pipe length and per-foot range, and put the stand, core cutting and other lump sums in the fixed field.

Why longer pipe runs cost more than just pipe

Performance: Every AC has a recommended maximum pipe length and height difference in its installation manual. Longer runs reduce efficiency slightly and may need extra refrigerant.
Extra gas: Some manufacturers specify additional charge per metre beyond a certain length. If your installer adds gas, ask how much and why.
Joints: Long runs sometimes mean extra flare or brazed joints, each a possible leak point.

Keeping the outdoor unit close to the indoor unit, with a short and direct pipe run, is cheaper and usually better for the AC.

How to check the bill

Before installation, ask for the rate card from the brand or dealer and the length of pipe included.
During installation, measure the pipe used with a tape (outdoor to indoor unit along the route) or count the coil left over.
Check that vacuuming was done; a vacuum pump should be connected for some minutes before the gas is released.
Check the outdoor unit placement: airflow, shade where possible, not in a closed duct (installation mistakes).
Ask for an itemised bill with GST shown separately, and keep it with the warranty card.
If the bill shows more pipe than you measured, raise it then, before paying.

Brand installation vs local technician

Point	Brand's authorised installer	Independent local technician
Warranty	Usually needed to keep the product warranty valid	May void warranty; check terms
Rates	Published rate card in many cases	Negotiable; may be lower or higher
Accountability	Complaint through brand helpline	Directly with the technician
Timing	Slots may be tight in peak summer	Often faster

Many warranties require installation by the brand or its authorised partner. Read the warranty card before choosing. See warranty claims rejected.

Also budget for

An AMC after the warranty period: see AMC contracts.
A stabiliser if your area has very poor voltage and the brand recommends one.
An increase in sanctioned load with your DISCOM if your connection is small.

FAQ

Is 'free installation' really free?

The basic part usually is, if it is stated on the invoice or offer. Extras are charged. Ask what the free part includes before purchase.

Can I reuse the old copper pipe?

Sometimes, if it is the right diameter, in good condition and properly flushed. Many installers and brands prefer new pipe, especially when the refrigerant differs. Ask the brand.

Is aluminium pipe acceptable?

Some installers offer cheaper alternatives. Joints between dissimilar metals can corrode. Follow the AC manufacturer's installation manual.
